Yellow bluestem *(Bothriochloa ischaemum*) is a new species to Saguaro
National Park (Tucson, Arizona). It showed up at an isolated spot in one of
the riparian areas. I haven't been able to find much information about this
Folks in (www.texasinvasives.org) do not seem to like it. Does any one know
how invasive it is? What are the ecological threats of this plant? Best
control measures? Any information you can provide would be helpful.
